What is the most efficient or recommended way to parse numbers in Mathematica? I can use ToExpression["1234"] and it will return the number. But this won't do, because I could be scraping un-trusted data and the above could lead to an injection of code. I could also use something like this: ToExpression[StringCases["1234", x1 : NumberString ~~ ___ -> x1]] but then I have to add error checking and whatnot. I suppose I could write a simple MathLink program which implement atoi, atol, etc. All of these solutions seems like a lot of overhead. Anybody have a better idea? Thanks, Michael
